Answer 4

principal quantum number

measures energy level
The energy and distance from the nucleus.

Question 5

l

Answer 5

Angular momentum quantum number

identifies The subshell - orbital shape

Question 6

ml

Answer 6

magnetic quantum number

identifies The orbital orientation.

Question 7

emission happens when

Answer 7

the electron goes down an energy level

Question 8

absorption happens when

Answer 8

the electron goes up an energy level

Question 9

Diamagentic

Answer 9

All electrons are paired –> causes to repel other electrons

Question 10

paramagentic

Answer 10

Not all electrons are paired

–> causes to attract other electrons

Question 11

Rutherford’s experiment proved

Answer 11

most of the atom is empty space, and the protons are in the nucleus

Question 12

Quantum theory proves

Answer 12

electrons are in an electronic cloud around the nucleus

Question 12

Bohr Model theories

Answer 12

electrons are in orbits around the nucleus at quantized energy levels.

Question 13

Pauli Principle

Answer 13

no two electrons in the same atom can have identical values for all four of their quantum numbers.

Question 13

What is the ground state electron configuration for Co2+?

Answer 13

ar 3d7

Question 13

The Aufbau Principle

Answer 13

electrons fill lower-energy atomic orbitals before filling higher-energy ones

Question 14

ml can be what values

Answer 14

-l <= m <= l

Question 15

l can be what values

Answer 15

l = n-1

Question 16

m spin can be what

Answer 16

+1/2 or -1/2

Question 17

Effective Nuclear Charge

Answer 17

combination of attractive forces between electrons and the nucleus and electron–electron repulsive forces

Question 18

Ionization energy

Answer 18

is the amount of energy required to remove an electron from a gaseous
atom.

Question 19

Electron Affinity

Answer 19

is the energy change when a gaseous atom gains an electron

Question 20

Hunds Rule

Answer 20

every orbital in a subshell is singly occupied with one electron before any one orbital is doubly occupied, and all electrons in singly occupied orbitals have the same spin.
